=== Introduction ===
* 2.      Chest Width
In many conformation systems for dairy goat defects are scored when scoring animals for linear traits and general characteristics. Defects are not there to describe the whole variation in the population, but only if a problematic trait (e.g. side leak) can be detected. The number of defects scored should be kept as low as possible. This chapter describes characteristics of some known defects for dairy goats. They are considered to be important for dairy goats and could be used by countries or organizations that do not yet score them. If a country or organization already has a list of defects, they could consider aligning their list with the ICAR list.

=== Common standard traits ===
=== Description of defect ===
The easiest way to score conformation defects digitally, is when a goat is scored for a group of linear traits (frame, legs/feet, udder); the classifier is requested by the system if there are any specific defects within this particular group.


* 21.    Hock development
The advantages of scoring defects are:
* 22.   Bone structure
* 23.    Rear udder width
* 24.   Teat thickness
* 25.   Muscularity


=== Standard trait definition ===
# Get overview what the status of a specific defect is in the population
The precise description of each trait is well defined and it is essential that the full range of linear scores to identify the intermediate and extremes of each trait be used. The assessment parameters for the calculations should be based on the expected biological extremes of a cow in the first lactation. The scale must cover the biological extremes of the current population.
# Could be used for determining the score for general characteristics
# Could be used to present figures per sire


Recommended Scale 1 - 9
Disadvantage of scoring defects:


'''Note''': The linear scale used, must cover the expected biological extremes of the population in the country of assessment.
# Difficult to harmonize classifiers as definitions are not always clear and for training sessions it is very hard to find a group of goats representing all defects.


==== 1. Stature ====
Defects can be scored with 0 (not present), 1 (slightly present) or 2 (pronounced defect). More practical is that classifier score defects only when they are present, 1 (slightly present) or 2 (pronounced defect).
Reference point: Measured from the top of the spine in between hips to ground. Precise measurement in centimetres or inches, or linear scale.

:The precise description of each trait is well defined and it is essential that the full range of linear scores to identify the intermediate and extremes of each trait be used. The assessment parameters for the calculations should be based on the expected biological extremes of the same category animals in terms of sex and age scored. The scale must cover the biological extremes of the current population or category. The extremes and the intermediates are ordered according to the degree of expression of the trait. For example thin and thick, long and short etc. A high or a low score has no particular meaning and it is not necessarily desirable or undesirable.

== Appendix 4: The standard trait definition for Dairy Goats ==
==== 29. Rear legs rear view ====
The ICAR multi dairy goat breed conformation recording recommendation describes a set of conformation traits which are currently used in several countries in several breeds. The traits are defined in such a way that they are not breed specific.  
Reference point: Direction of the feet of the rear legs, viewed from the rear.


This document contains a list of standard traits, which is a list of traits which could be scored by all organisations in the same way to improve further harmonisation on international level. Conformation traits are important as auxiliary traits. Linear type scoring can also help to improve machine milkability in goats.

=== '''Trait definitions''' ===
                       5 - Intermediate


==== '''Linear Type Traits''' ====
                       9 - Toes out
Linear type traits are the basis of all modern type classification systems, and are the foundation of all systems for describing the dairy goat. Linear classification is based on measurements of individual type traits instead of opinions. It describes the degree of a trait, not its desirability.
[[File:S5-Appendix3-Fig.29.jpg|center|thumb|600x600px|'''Section 5. Appendix 3. Figure 29: Rear legs rear view''']]


Advantages of linear scoring are:
==== 30. Rear legs side view ====
Reference point: Angle measured at the front of the hock.


* Traits are scored individually
                       1 - Straight
* Scores cover a biological range
* Variation within traits is identifiable
* Degree rather than desirability is recorded


==== '''Standard Traits''' ====
                       5 - Intermediate
The standard traits satisfy the following conditions:


* Linear in a biological sense
                       9 - Sickled
* Single Trait
[[File:S5-Appendix3-Fig.30.jpg|center|thumb|600x600px|'''Section 5. Appendix 3. Figure 30: Rear legs side view''']]
* Heritable
 
* Economic value; Direct or indirect with reference to the breeding goal
==== 31. Hind pasterns side view ====
* Possible to measure instead of score
Reference point: Angle of the pasterns of the rear legs with the floor 
* Variation within the population
* Each linear trait should describe a unique part of the goat which is not covered by a combination of the other linear traits

=== Standard Trait Definition ===
                       1 - Low
The precise description of each trait is well defined and it is essential that the full range of linear scores to identify the intermediate and extremes of each trait be used. The assessment parameters for the calculations should be based on the expected biological extremes of the same category animals in terms of sex and age scored. The scale must cover the biological extremes of the current population or category. The extremes and the intermediates are ordered according to the degree of expression of the trait. For example thin and thick, long and short etc. A high or a low score has no particular meaning and it is not necessarily desirable or undesirable.


Recommended Scale 1 - 9
                       5 - Intermediate

Introduction

This document contains a description of conformation traits scored in dairy cattle breeds, dual purpose cattle, beef cattle breeds and dairy goats. For the four groups a separate trait list has been established. For the traits, trait definitions are given in wording and with drawings.

Besides giving trait definitions, recommendations are given on improvement and transparency of data collection and monitoring classifiers.

For the dairy, dual purpose and beef cattle breeds a recommendation on scoring conformation defects is given.

Linear and composite type traits

Linear Type Traits

Linear type traits are the basis of all modern type classification systems, and are the foundation of all systems for describing the animal. Linear classification is based on measurements of individual type traits instead of opinions. It describes the degree of trait not the desirability.

Advantages of linear scoring are:

  1. Traits are scored individually.
  2. Scores cover a biological range.
  3. Variation within traits is identifiable.
  4. Degree rather than desirability is recorded.

Standard traits

The standard traits satisfy the following conditions:

  1. Linear in a biological sense.
  2. Single Trait.
  3. Heritable.
  4. Economic value, direct or indirect with reference to the breeding goal.
  5. Possible to measure instead of score.
  6. Variation within the population.
  7. Each linear trait should describe a unique part of the animal which is not covered by a combination of the other linear traits.

Composite traits and general characteristics

Composite traits

  1. Composite traits are groups of linear traits relating to one specific area.
  2. The individual linear traits are weighted according to economic breeding objectives.
  3. The main composite traits for dairy cattle are: frame including rump, dairy strength, mammary, feet/legs.
  4. The main composite traits for dual purpose breeds are: frame, mammary, feet/legs and muscularity.
  5. The main composite traits for beef breeds are: muscularity, type (breed standard), feet/legs, development and final score.
  6. The main composite traits for dairy goats are: frame, udder, feet/legs and final score.

General characteristics

Type classification programs also include phenotype assessment. These are described as general characteristics or combined traits, which are not linear in a biological sense. A subjective score is given for the desirability of the animal according to the breeding goal.

  • Female animals for dairy and dual purpose breeds are inspected, classified and assigned grades/scores ranging from 50-97 points.
  • For beef breeds animals are inspected, classified and assigned grades/scores ranging from 60-99 points.
  • Dairy goats are inspected, classified and assigned grades/scores ranging from 1-9 points.

The most common scale for mature cows (second or more lactations) in points are described in Table 1.

Table 1. Range of scores for general characteristics or combined traits for cattle of dairy, dual purpose and beef breeds and for dairy goats.
Dairy and dual purpose breeds Beef breeds Dairy goats
Excellent 90 - 97 90 - 99 9
Very Good 85 - 89 85 - 89 7 - 8
Good Plus 80 - 84 80 - 84 4 - 6
Good   79 - 75 79 - 75 2 - 3
Fair/Poor/Insufficient 50 - 74 60 - 74 1


The awarding of classification grades varies in each country depending upon the breeding goals, and therefore classification scores must be considered in the context of the country of inspection.

The final class and score are derived from a breakdown of the main functional areas of the female:

  • For dairy cattle: 1) Frame including Rump, 2) Dairy Strength, 3) Mammary System and 4) Legs/Feet.
  • For dual purpose cattle: 1) Frame, 2) Mammary System, 3) Feet & Legs and 4) Muscularity.
  • For beef breeds: 1) Muscularity, 2) Type (breed standard), 3) Legs/Feet and 4) Development.
  • For dairy goats: 1) Frame, 2) Udder and 3) Legs/Feet.

For the quality of data for beef breeds it is important to score the traits for categories of similar age or sex. For example:

  • Calves at weaning (5-10 months).
  • Heifers: 6 months before calving.
  • Cows: between first and second calving.

For the quality of data of dairy goats it is important to score the traits for categories of similar age or sex.

The weighting of the component breakdown scores should meet the breeding goals in the Country of inspection.

  • It is recommended that for first lactating cows of dairy and dual purpose breeds the range of scores used is 70 - 90 points. The average score is always in the middle of the maximum and minimum a first lactating cow can be awarded.
  • For beef breeds it is recommended that for animals the range of scores used is 60 - 99 points. In the case of the range 60 - 99, the population average should be close to 80.

For dairy goats it is recommended that for animals the range of scores used is 1 - 9 points. The average score is always in the middle of the maximum score and the minimum score the group (for example population within a country) can be awarded. In the case of the range 1 - 9, the population average should be close to 5.

Genetic evaluation of dairy and dual purpose animals

Type inspection system - Genetic evaluation

  1. Breeding values for bulls and cows to be based on the classification of cows in the first lactation scored in a herd evaluation system.
  2. In a herd evaluation system all first lactating cows, which have not be previously evaluated, must be scored during the visit of the classifier
  3. Additional classifications to obtain a bull proof may only be possible if completed by the same organisation and daughters are sampled randomly with sufficient number of herd mates (contemporaries) scored during the same visit. A minimum of 5 first lactating cows, which qualify for genetic evaluation, are inspected at the same visit      

Evaluation model

  1. Modern BLUP evaluation techniques should be used to obtain accurate unbiased evaluations.
  2. Data should be corrected for influencing factors such as age, stage of lactation and season by the model. Classifiers should not make adjustments during scoring.
  3. Corrections for variation between classifiers are required to avoid heterogeneity of variance.
  4. Herd mates are defined as the contemporaries of the evaluated heifers in the same lactation, scored during the same visit by the same classifier.

Publication of information

  1. Publish bull-proofs around an average of 0 and a genetic standard deviation of 1.0.
  2. Proofs of widespread bulls should be published as bar graphs covering the range between +3 and -3 standard deviations.
  3. Or: Mean of 100 & the standard deviation in the base population where this standard deviation is adjusted to the situation the proofs of cows have a reliability of 100%.
  4. The base of sire and cow evaluation should follow the definition of the production proofs, given by Interbull. This includes a stepwise fixed base that should be renewed every five years. The base is defined by cows born 5 years previously.

Conformation recording of dairy cattle

The ICAR multi dairy breed conformation recording recommendation integrates with the World Holstein-Friesian Federation guidelines on the international harmonization of linear type assessment, trait definition, evaluation standards and publication of type proofs for bulls.

This document contains a list of approved standard traits, which is a list of traits which should be scored by all organisations in the same way to improve further harmonisation on international level, also on Interbull level. The data collected within these recommended standards qualifies for MACE evaluation by Interbull.

Further the document contains a list of 5 traits which are commonly used by organisations in the dairy and dual-purpose breeds world-wide. This list of common standard traits is added to improve harmonisation of these traits too.

Besides giving trait definitions on standard traits, recommendations are given on improvement and transparency of data collection and monitoring classifiers.

The list with standard traits and the standard trait definition for Dairy Cattle can be found in Appendix 1: The standard trait definition for Dairy Cattle.

Conformation recording of dual purpose cattle

This document contains a list of approved standard traits, which is a list of traits which should be scored by all organisations in the same way to improve further harmonisation on international level, also on Interbull level. The data collected within these recommended standards qualifies for MACE evaluation by Interbull.

Further the document contains a list of 5 traits which are commonly used by organisations in the dairy and dual-purpose breeds world-wide. This list of common standard traits is added to improve harmonisation of these traits too.

Besides giving trait definitions on standard traits, recommendations are given on improvement and transparency of data collection and monitoring classifiers.

The standard trait definition for Dual Purpose Cattle can be found in Appendix 2: The standard trait definition for Dual Purpose Cattle.

Conformation recording of beef cattle

The ICAR multi beef breed conformation recording recommendation describes a set of conformation traits which currently are used in several countries in several breed. The traits are defined in such a way that they are not breed specific.

This document contains a list of standard traits, which is a list of traits which could be scored by all organisations in the same way to improve further harmonisation on international level.

The list with standard traits and the standard trait definition for Beef Cattle can be found in Appendix 3: The standard trait definition for beef breeds

Conformation recording of dairy goats

The ICAR multi dairy goat breed conformation recording recommendation describes a set of conformation traits which currently are used in several countries in several breed. The traits are defined in such a way that they are not breed specific.

This document contains a list of standard traits, which is a list of traits which could be scored by all organisations in the same way to improve further harmonisation on international level.

The list with standard traits and the standard trait definition for dairy goats can be found in Appendix 4: The standard trait definition for dairy goats

Improving data quality and monitoring classifiers

Introduction

When collecting data on animal performances on a routine basis it is important to do this in a consistent and transparent way. In this way quality of data can be guaranteed and for everybody it is clear how it is done. This is also important for scoring animals for conformation traits, which is normally done by classifiers, specially trained doing this job.

This chapter describes the improvement of quality and transparency of data collection for conformation traits.

Practical aspects of type classification system

One organisation should be in charge of classifications within each evaluating system.

There should be a head-classifier in charge of training and supervising other classifiers within the evaluating system to achieve and maintain a uniform level of classification. Additionally the exchange of information between head-classifiers from different systems/countries is recommended.

Individual full time professionals should complete classification. Classifiers should be independent of commercial interest in AI-bulls/studs.

Classifiers must record the trait as observed without adjustment e.g. Age, stage of lactation, sire or management system.

The working information provided for the classifier should make no reference to the pedigree or performance of the animal.

Classifiers should always rotate classification areas (herds and regions) to ensure a good data connection between regions and to minimise the sequential scoring of animals by the same classifier. This way of working reduces this risk of classifier times regional genetics interaction or classifier times herd interaction.

An advisory group can be installed with expertise in the field of conformation classification, statistics, breeding, training people, in order to monitor and advise on the improvement to the classification system.

All factors accounting for any non-genetic variance should be recorded when a herd is visited, e.g. classifier's identification, date/time of scoring, management group, housing system, flooring, nutritional status. This makes it possible to find possible interactions between the environmental factors and the trait scored.

Types of housing can be free stall, tie stall, mixture (stall plus outside).

Types of floors can be concrete, cement with groves, slats, sand, rubber, straw, pasture.

Training and monitoring of classifiers

The monitoring and performance evaluation of classifiers is an important part of the standardisation of the ICAR international type program.

Objectives

Improve accuracy of data collection, within country all classifiers should:

  1. Apply the same trait definition
  2. Apply the same mean.
  3. Apply the same spread of scores.

Tools for objective 1:

  1. National group training sessions.
  2. Statistical monitoring of individual classifiers performance with reference to mean, spread and normal distribution of scores.
  3. Compute the correlation between the scores of one classifier and the group by using bivariate analysis. This shows the quality of harmonisation of trait definition between classifiers.
  4. Improve the genetic correlation for linear traits between countries (Interbull evaluation)
  5. Apply the same trait definition in all countries.

Tools for objective 2:

  1. International training of head classifiers.
  2. International group training sessions.
  3. Audit system.

If a country decides to change the definition of a trait, it is recommended not to use previous scores or use only as a correlated trait in the national genetic evaluation system.

National group training sessions

One way of improving harmonisation of scoring by classifiers is having regular training sessions with a group of classifiers.

There are many ways to accomplish trait harmonisation through training sessions. Normally a training session consists of scoring a group of animals and the scores of individual classifier are compared with the scores of the other classifiers and/or head classifier.

Attention points are:

  1. Use a group of animals for training session which is representative for the population classifiers have to score during their herd visits.
  2. Deviations of individual scores are discussed and it is made clear which is the correct score for a certain trait on an animal.
  3. Scores of each classifier are analysed per trait using some analysis tools:
    • Compute the mean and standard deviation of the deviations of the scores on animals per trait, per classifier. The deviation is the difference between the score and the average group score for a trait, for an animal. This gives insight in the scoring of individual classifier: always above or below the mean, more variation in scoring a trait than the group/head classifier. (with a test it can be shown if the differences found are significant).
    • Compute the spread of the deviation of scores given by classifier per trait. This gives insight in how consistent a classifier is scoring a trait. (with a test it can be shown if the differences found are significant).
  4. Instead of scoring a group of animals once, the animals can be scored twice by the classifiers, for example in the morning and in the afternoon. Based on these scores (approximately 20) the repeatability per classifier per trait can be computed.

Statistical monitoring of individual classifiers

The scores of a classifier from a certain period in time can be analysed. A period can be 12 or 6 months, for example.

From these scores the mean and standard deviation can be computed. The mean should be close to (maxscore-minscore)/2, and the standard deviation should be near (maxscore-minscore+1)/6, where minscore is the lowest score on the scale and maxscore is the highest score on the scale. For example: scoring a trait on a scale of 1-9, a mean is expected of 5 and a standard deviation of 1.5.

Another option is to compute the correlation between the scores of one classifier and the scores of rest of the group by using bivariate genetic analysis. This shows the quality of harmonisation of trait definition between classifiers (Veerkamp, R. F., C. L. M. Gerritsen, E. P. C. Koenen, A. Hamoen and G. de Jong. 2002. Evaluation of classifiers that score linear type traits and body condition score using common sires. JDS 85:976-983).

For this analysis, two data sets are created, one with scores of one classifier and the other with scores of all other classifiers from a certain period, for example 12 months. Both data sets can be analysed in a bivariate analysis, estimating different (genetic) parameters. The analysis can be carried out for each trait and for each classifier. From the bivariate analyses the following parameters can be derived:

  1. Heritability: the heritability estimated within each classifier can be used as criteria for the repeatability of scores within classifiers, albeit the optimum value is not unity but depends on the true heritability of each trait.
  2. Genetic correlation: the genetic correlation between two data sets can be used as a measure of the repeatability between classifiers, where a genetic correlation of one between classifiers is expected.
  3. Genetic standard deviation.
  4. Phenotypic standard deviation (= square root of genetic variance and error variance).

For the evaluation of each trait for each classifier the diagram in Figure 1 can be used.

Evaluation obviously starts with the mean score for each classifier, i.e., the mean should be close to the trait standard (5 for linear traits and 80 for descriptive traits). Secondly, the genetic standard deviation should not be lower than the average.

Figure 1. Scheme for evaluation trait by classifier using genetic parameters.

If the genetic standard deviation is lower, this could be due to the scale used (measured by the phenotypic standard deviation), due to poor within classifier repeatability (a low heritability) or both. If the low genetic standard deviation goes together with a low phenotypic spread, the advice is the classifier should use the scale in a better way, use more the extreme scores. If the genetic spread goes together with a low heritability, then the classifier should score the trait more consistently, apply the same definition.

If the genetic correlation is too low the classifier is likely to score a trait different than other classifiers.

All the parameters from the system can be tested using the standard error on the parameters estimated. Every classifier can be tested against the average of the parameters of all classifiers for a certain trait. A classifier with a few scores may deviate a bit more from the average of the group, therefore taking the standard error into account in a statistical test is more fair.

Auditing a classification system

The Classification system applied can be further improved by using an audit system where experts familiar with the conformation classification in other countries or organisations, examine the situation in your organisation or country.

An important issue is that information is exchanged between people responsible for the classification system.

Different options to audit are:

  1. By using international workshops, in which information can be informally exchanged regarding how classifiers are trained and conduct their daily work
  2. By inviting classifiers and/or a head classifier from another country or organisation to participate in or lead group training sessions
  3. By having a group of experts visit an organisation responsible for classification, conduct a survey on methods and procedures, report their findings and makes suggestions for improvements.

Recommendation on scoring conformation defects in cattle

Introduction

In many conformation systems for cattle defects are scored when scoring animals for linear traits and general characteristics. Most of the time defects are used to determine the score for general characteristics.

This chapter describes characteristics of defects for dairy, dual purpose and beef cattle and contains a list of proposed defects which could be used. They are considered to be important for one of the breed types (dairy, dual purpose and/or beef) and could be considered by countries or organizations, that do not score them up to now. If a country or organization has already a list of defects, they could consider to reduce the list according to the ICAR list.

Description of defect

Defects are not there to describe the whole variation in the population, but only a problematic trait (e.g. side leak) or a trait with a high enough frequency in the population.

The number of defects scored should be kept as low as possible as more defects means also more labor.

The easiest way to score conformation defects in a digital system is when a cow is scored for a group of the linear traits (frame, dairy strength, mammary system, legs/feet), the classifier is requested by the system if there are any defects within this particular group.

A conformation defect could be scored when it has the following characteristics:

  1. Heritable.
  2. Not rare.
  3. iI problematic for functionality.
  4. Is clearly described and visible.
  5. Should be scored as 0/1/2 (as soon as there is more variation and the frequency in population is considerable, one could/should consider to score this trait as a linear trait (scale 1-9).
  6. Is used to come up with a score for a general characteristic.

Defects have no value to be scored when it is not used in determining general characteristics or when it is not used in a genetic evaluation.

The advantages of scoring defects are:

  1. Get overview what the status of a specific defect is in the population.
  2. Could be used for determining the score for general characteristics.
  3. Could be used to present figures per bull.

Disadvantage of scoring defects:

  1. Difficult to harmonize classifiers as definitions are not always clear and for training sessions it is very hard to find a group of cows representing all defects.

Defects can be scored with 0 (not present), 1 (slightly present) or 2 (pronounced defect). More practical is that classifier score defects only when they are present, 1 (slightly present) or 2 (pronounced defect).

Relationship between conformation and functional traits for dairy and dual purpose cattle

General considerations on the use of conformation data for longevity source

Conformation appraisal of cattle was introduced with the goal of comparing animals with breed standards (true type model). An additional goal of conformation recording was to be a simple predictor of production potential and longevity.

Since these times, many new traits have been recorded and evaluated for dairy and dual-purpose cattle regarding health and longevity. These traits have been supplemental to conformation recording and have even replaced them for certain purposes.

However, conformation recording is still an efficient way to assess many cows during a relatively short period of time and requires less commitment and time from the dairy producer to collect the data.

The usefulness of this data for the prediction of health and longevity should be considered in the setting up of a conformation recording system.

In Appendix 5, the relationship between some of the ICAR standard conformation linear traits for dairy and dual-purpose cattle and health and longevity is described in detail. This information can be used to show farmers how the conformation scores can help him to breed a kind of cow which is able to perform the best in the herd.

Guidelines on usage of data from AMS systems to derive udder conformation traits

Introduction

To collect information on quality of conformation of udders, the udders of dairy cows are scored by professional classifiers. In the ICAR guidelines several linear udder conformation traits are defined for Dairy Cattle (Appendix 1) and Dual Purpose Cattle (Appendix 2).

High genetic correlations have been reported in literature between linear scored traits and the same traits based on data from automatic milking systems (AMS) (Byskov et al., 2012; Poppe et al, 2019). The advantage of using data from AMS is that information is collected continuously during the whole lactation and also over lactations. In a regular classification system a cow is scored only once during her life, at one moment in the first lactation. Further the collection of data via an AMS system is cost effective.

Description of AMS data about udder traits

In AMS information is stored about the positions of teats to be able to attach the milk cups in a short time. The storage or information of the teat positions can be different across manufacturers, but at the end the positions of all four teats are determined by an AMS and are stored.

Based on teat positions, five different udder traits can be derived. Each milking record contained Cartesian coordinates (x, y, z) of each of the 4 teats, indicating the 3-dimensional location of the teat tips. The z-coordinate is a measure of the distance from the teat tip to the floor, the y-coordinate is a measure of the position of the teat on the axis parallel to the long side of the robot, and the x-coordinate is a measure of the position of the teat on the axis perpendicular to the long side of the robot. The Cartesian teat coordinates in the AMS data set can be used to calculate the udder conformation traits: rear teat distance (RTD), front teat distance (FTD), udder depth (UD), distance between front and rear teats (DRF) and udder balance (UB, the difference in depth between front and rear udder). A specification of the udder conformation traits and equations for calculation are given in Table 3.

The trait rear teat distance is similar to rear teat placement, and front teat distance is similar to the trait front teat placement. Rear teat placement, front teat placement and udder depth are currently in the ICAR list of conformation traits for dairy and dual purpose cattle.

Table 3. Calculation of udder conformation traits based on teat positions measured by AMS.

Udder trait Description Calculation1
UD Average distance of teat ends to the floor in mm (Zlf + Zrf + Zlr + Zrr)/4
FTD Distance between left and right front teat ends in mm Xlf - Xrf
RTD Distance between left and right rear teat ends in mm Xlr - Xrr
UB Average difference in distance to the floor between the front and rear teat ends in mm (Zlr + Zrr)/2 - (Zlf + Zrf)/2
DRF Average distance between the front and rear teat ends in mm (Ylf + Yrr)/2 - (Ylf + Yrf)/2

1Z = Z-coordinate, Y = Y-coordinate, X = X-coordinate, lf = left front, rf = right front, lr = left rear, rr = right rear.

Edits screening AMS data

When AMS data is used for analysis, checks need to be applied. Recommended edits are:

  1. Milking is not a failure or not refused;
  2. Milk yield is larger than 0 kg;
  3. Teat positions are known;
  4. Measures of z-coordinates (distance teat - floor) larger than 0 mm;
  5. Distances between left front and rear or right front and rear larger than 0 mm;
  6. Distance between left and right rear teats larger than -30 mm (A negative distance is possible in case of crossing teats. The distance depends on the order of attaching the cups, if for example the left teat is stored as left teat or as right teat.);
  7. Distance between left and right front teats larger than 0 mm;
  8. Observation deviates less than 4 standard deviations from the expected observation of an animal;
  9. At least 5 hours interval with previous milking;
  10. Measurements are available on all four teats. So, data of cows with less than four milking quarters has to be removed.

Fields required using information form AMS:

  1. Animal ID.
  2. Herd ID.
  3. Date and time of miking.
  4. x, y, z coordinates.
  5. Milk yield.
  6. Information on success of milking.

Analysis of data in genetic evaluation

From the AMS, information of every separate milking more than 700 measurements are made available during a lactation. To analyze the data in genetic evaluations several options are possible:

  • Usage of all measurements.
  • Usage of every xth measurement.
  • Usage of average of n-measurements (e.g. 10) or of a certain period (e.g. week).

Considerations

  • Determined teat positions are actually the position of teat ends. In case trait udder depth is derived from teat positions, one also should or could consider teat length to get a more exact measure of udder depth. This correction only is possible in case the AMS system is also determining teat length.
  • Further it should be noticed that stature of the cow affects the distance from floor to udder (z coordinate). It also should be noticed that scoring udder depth by classifiers, udder depth is scored in relation to the hock (as reference point). This also results in the situation that udder depth scored by classifiers is also affected by stature.
  • When using udder depth data from AMS for genetic evaluation one always should check the genetic correlation between udder depth scored by classifiers and udder depth based on AMS data. A way to improve the genetic correlation is to add the breeding value for stature and teat length as extra effects to the model for udder depth based on AMS data.
  • In the future, data from AMS might also become available from udder traits like teat length, teat direction or teat thickness.

Recommendation on scoring conformation defects in dairy goats

Introduction

In many conformation systems for dairy goat defects are scored when scoring animals for linear traits and general characteristics. Defects are not there to describe the whole variation in the population, but only if a problematic trait (e.g. side leak) can be detected. The number of defects scored should be kept as low as possible. This chapter describes characteristics of some known defects for dairy goats. They are considered to be important for dairy goats and could be used by countries or organizations that do not yet score them. If a country or organization already has a list of defects, they could consider aligning their list with the ICAR list.

Description of defect

The easiest way to score conformation defects digitally, is when a goat is scored for a group of linear traits (frame, legs/feet, udder); the classifier is requested by the system if there are any specific defects within this particular group.

The advantages of scoring defects are:

  1. Get overview what the status of a specific defect is in the population
  2. Could be used for determining the score for general characteristics
  3. Could be used to present figures per sire

Disadvantage of scoring defects:

  1. Difficult to harmonize classifiers as definitions are not always clear and for training sessions it is very hard to find a group of goats representing all defects.

Defects can be scored with 0 (not present), 1 (slightly present) or 2 (pronounced defect). More practical is that classifier score defects only when they are present, 1 (slightly present) or 2 (pronounced defect).

Approved standard defects

The list with approved conformation defects is shown in Table 4 below.

Appendix 4: Conformation recoding of Dairy Goats

The ICAR multi dairy goat breed conformation recording recommendation describes a set of conformation traits which are currently used in several countries in several breeds. The traits are defined in such a way that they are not breed specific.

This document contains a list of standard traits, which is a list of traits which could be scored by all organisations in the same way to improve further harmonisation on international level. Conformation traits are important as auxiliary traits. Linear type scoring can also help to improve machine milkability in goats.

Trait definitions

Linear Type Traits

Linear type traits are the basis of all modern type classification systems, and are the foundation of all systems for describing the dairy goat. Linear classification is based on measurements of individual type traits instead of opinions. It describes the degree of a trait, not its desirability.

Advantages of linear scoring are:

  • Traits are scored individually
  • Scores cover a biological range
  • Variation within traits is identifiable
  • Degree rather than desirability is recorded

Standard Traits

The standard traits satisfy the following conditions:

  • Linear in a biological sense
  • Single Trait
  • Heritable
  • Economic value; Direct or indirect with reference to the breeding goal
  • Possible to measure instead of score
  • Variation within the population
  • Each linear trait should describe a unique part of the goat which is not covered by a combination of the other linear traits

3.1.4 Composite traits and general characteristics

3.1.4.1 Composite Traits
  1. Composite traits are groups of linear traits relating to one specific area.
  2. The main composite traits are – Frame, Udder, Feet/Legs and Final Score.
3.1.4.2 General Characteristics
  1. Type classification programmes also include phenotype assessment. These are described as general characteristics or combined traits, which are not linear in a biological sense. A subjective score is given for the desirability of the animal according to the breeding goal.
  2. Animals are inspected, classified and assigned grades/scores ranging from 1-9 points.
  3. The most common scale is reported in table 5, below reported.
  4. The awarding of classification grades varies in each country depending upon the breeding goals, and therefore classification scores must be considered in the context of a breed in the country of inspection.
  5. The final class and score are derived from a breakdown of the main functional areas of the animal, groupped for Frame, Udder or Legs/Feet
  6. For the quality of data, it is important to score the traits for categories of similar age or sex. It is recommended to score goats in the 1st (standard) lactation and bucks within the 1st year, starting at 5 months of age.
  7. The weighting of the component breakdown scores should meet the breeding goals in the breed and country of inspection. It is recommended that for animals the range of scores used is 1 – 9 points. The average score is always in the middle of the maximum score and the minimum score the group (for example population within a country) can be awarded. In the case of the range 1-9, the population average should be close to 5.

Appendix 5: Relationship between conformation and functional traits for dairy and dual purpose cattle

Introduction

In this appendix, the relationship between some of the ICAR standard conformation linear traits for dairy and dual-purpose cattle and health and longevity is described in detail. This information can be used to show farmers how the conformation scores can help him to breed a kind of cow which is able to perform the best in the herd.

Results are presented as a deviation in percentage of the phenotypic standard deviation of 6 functional traits:

  • Lifetime production: milk production during the whole productive life
  • Survival: binary trait for reaching the 4th calving
  • Somatic cell count: geometric mean of 1st lactation SCC
  • Claw disorders: any disorder observed on the hoof for the disorders sole haemorrhage, digital dermatitis, interdigital dermatitis, sole ulcer, interdigital hyperplasia, and white line disease
  • Interval from 1st to last insemination: interval in days between 1st to last insemination resulting in a gestation.
  • Calving ease: calving score on a scale of 1 to 4 (easy to caesarean section) at the 1st calving. All animals in the analysis had the opportunity to have a productive life of at least 36 months.

Results are based on analyses conducted in 4 populations, three Holstein populations from Hungary, Netherlands and Switzerland, and the Fleckvieh population from Germany. Only 1st lactation classifications were used for the analysis. A more detailed description of the data can be found in Table 1.

The relationships found were very similar for the different populations. Therefore, for each conformation trait the relationship shown in this document is based on data of one population, which is indicated per trait in Table 1. Further, Table 1 shows the number of records used for every conformation trait – functional trait combination, as also the period of the scores.

Stature

Stature

Stature is clearly a trait with an intermediate optimum. Very small cows have a lower lifetime production. Their smaller size has no effect on the level of culling rate, so the lower lifetime production is more likely due to lower production per lactation. On the other side of the scale tall cows have a much lower survivability - possibly because of health issues related to their size - which in turn impacts their lifetime production.

Section 5. Appendix 5. Figure 1: Stature

Chest width

The graph shows, that both survival and lifetime production are decreasing when the linear score of the cows move down or up from the middle of the scale. When the chest is narrow the cow has not enough strength to ensure a good lifetime production and survival. When the chest is wider, the cows become “too wide”, they do not represent their age, they look like a mature cow in their young age. This influences the efficiency of the survival and through this, the lifetime production in a negative way.

Section 5. Appendix 5. Figure 2: Chest width

Body depth

Body depth has an intermediate optimum in relation to survival and fertility. Deeper cows in 1st lactation, tend to have a reduced fertility (longer interval 1st to last insemination) and a shorter productive life, which results in a lower lifetime production. The effect of shallow cows is only a reduced lifetime production. Fertility does not seem to be hindered in those cows.

Section 5. Appendix 5. Figure 3: Body depth

Angularity

Angularity does not show any relationship with fertility. However, cows with a higher score for angularity have, on average, a higher lifetime production. This relationship is much stronger for Angularity scores below average than above average and is based on the highly positive relationship between production and angularity.

Section 5. Appendix 5. Figure 4: Angularity

Rump angle

For most of the scale, Rump Angle does not have any strong relationship with the traits we analyzed. There is no relationship to calving ease. The relationship with survival is only present for extreme scores. This outcome shows that Rump Angle in relation to survival could be considered more as a defect, than a true linear trait.

Section 5. Appendix 5. Figure 5: Rump angle

Rump width

As shown in the graph, the analyses did not detect any serious effect of Rump Width on calving ease. Beside this finding, extreme narrow rumps have a negative effect on lifetime production. The effect is larger for lifetime production than for survival. The reason might be that narrower rumps lead to narrower udders and lower milk production. On the other side wide-rumped cows are usually large cows. It has been shown that big cows have a reduced lifetime production and survival.

Section 5. Appendix 5. Figure 6: Rump width

Rear legs rear view

There is a strong relation between hocked-in rear legs and claw disorders. Leg position with extreme toe-out implies a bad foot position. This can influence the susceptibility to claw diseases. It is probably this relationship that explains the reduced survival and lifetime production of cows with low score for Rear Legs Rear View. For above average score for Rear Legs Rear View there is no relation anymore with the three analyzed traits.

Section 5. Appendix 5. Figure 7: Rear legs (rear view)

Rear legs set

Rear Legs Set is a trait with an intermediate optimum. Based on the data, both extremes, straight or sickled, show a tendency to reduced performance for functional traits. However, cows with sickled legs are more susceptible to claw problems and reduced lifetime production than those with straight legs.

Section 5. Appendix 5. Figure 8: Rear legs set

Foot angle

Cows with very low Foot Angle are much more susceptible to claw disorders than those with steeper Foot Angle. Steep Foot Angle is only a problem when it is extreme, especially a score for less than average angle. Survival and lifetime production are lower as well for cows with low Foot Angle.

Foot Angle is highly correlated with hoof height. Above average hoof height (more angle) will allow the weight of the cow to be more evenly distributed on the hoof and can lead to less claw disorders. Cows with higher hoofs are more stable in different conditions (slatted floor, pasture). The thickness of the heel prevents some injuries.

Section 5. Appendix 5. Figure 9: Foot angle

Fore udder attachment

The Fore Udder Attachment does not have a large impact on udder health, survival or lifetime production, unless the attachment is very loose. For extreme loose Fore Udder Attachment an increase in somatic cell count is found.

Section 5. Appendix 5. Figure 10: Fore udder attachment

Front teat placement

Front Teat Placement does not have a strong association with any of the analyzed traits, except for extreme scores. Low value, that is teats which are to the outside of the quarters are often seen with cows having higher cell count and lower survival. Milkability with conventional milking systems is hindered when teats are far apart. This aspect might lead to a higher cell count.

Section 5. Appendix 5. Figure 11: Front teat placement

Teat length

As for Front Teat Placement, Teat Length is a trait with an intermediate optimum. However, the effect on survival and lifetime production is more important. Short teats are linked to a shorter productive life. On the other end of the scale, long teats are linked as well to shorter productive life. The association might be caused by teats being more prone to injuries or to infections.

Section 5. Appendix 5. Figure 12: Teat length

Udder depth

Udder depth is a trait with an intermediate optimum. It shows the most striking relation with health and longevity traits. A lower udder floor is related to a poor survival and lifetime production. Cows with this kind of udder are at higher risk of being culled as many difficulties might arise, such as udder health problems (also indicated by the higher somatic cell count), udder injuries, difficulties with the attachment of the milking machine, etc. The relationship at the high end of the scale (shallow udders) shows an interesting effect. Although survival remain high with higher udder floor, lifetime production plumets. Cows with a high score, are usually poor producers. Even though they live a rather long productive life, their lifetime production remains low.

Section 5. Appendix 5. Figure 13: Udder depth

Rear udder height

The association between lifetime production and Rear Udder Height is positive and nearly linear. The reason is to be found in a positive relationship with milk production, as there is more room to produce milk. But at the same time, higher rear udder makes it possible to have larger udders without lowering udder depth. These 2 elements combined result in not only a better lactation production, but rather a larger lifetime production. The association with survival and somatic cell count is minor.

Section 5. Appendix 5. Figure 14: Rear udder height

Central ligament

A strong Central Ligament is necessary to ensure that the udder is able to produce milk during a long time without becoming too deep after a several lactations. However, extreme depth of the udder cleft does not seem to be needed, as the effect of central ligament is non-existent from the middle of the scale onwards. But low scores for this trait are related to poor udder health and longevity. On the lower side of the scale, the relationship is like the one for Udder Depth and Front Teat Placement, showing that these traits describe in common the inability of the udder to last for multiple lactations.

Section 5. Appendix 5. Figure 15: Central ligament

Rear teat placement

The graph shows that Rear Teat Placement is a trait for which extremes should be avoided. Wide Rear Teat Placement (low score) is often related to a weak Central Ligament. This relationship could explain the lower survival and the high cell count associated with low scores for Rear Teat placement. It should be mentioned, regarding this trait, that an important part of the data comes from farms without robotic milking. Even though, rear teats which are placed close together are linked with a slightly lower survival.

Section 5. Appendix 5. Figure 16: Rear teat placement

Locomotion

The relation of locomotion with survival and lifetime production is strong. Lifetime production is much more reduced than survival in cows with a low score for locomotion. The cause of the association with claw disorder might be claw diseases leading to a bad locomotion as well as locomotion leading to claw diseases.

Section 5. Appendix 5. Figure 17: Locomotion

Body Condition Score (BCS)

For Body Condition Score, the most important association can be found with longevity traits, both survival and lifetime production. For both traits there is an intermediate optimum. Cows with extreme low score for BCS appears to have more claw disorders and higher interval between first and last insemination.

Section 5. Appendix 5. Figure 18: Body Condition Score (BCS)

Bone structure

The thickness of the bone has a weak relation with survival and lifetime production. Low values - meaning a coarse bone structure - are related to a lower survival.

Section 5. Appendix 5. Figure 19: Bone structure

Rear udder width

Rear Udder Width has a positive and nearly linear relationship with lifetime production. This relationship is like the one found with Rear Udder Height. The reason is that more room is available for milk production, without deepening the udder.

Section 5. Appendix 5. Figure 20: Rear udder width

Muscularity

Muscularity, a standard trait for dual purpose cattle, shows an intermediate optimum for survival and lifetime production. The use of Muscularity in linear description is also an indicator of functional traits. As with milk production, its optimum should be defined in relation to the breeding goal for meat production on one hand, and survival on the other hand.

Section 5. Appendix 5. Figure 21: Muscolarity

Fore udder length

Fore Udder Length, a second trait that is specific for dual purpose cattle, has an intermediate optimum for survival, and for lifetime production. Shorter fore udders are found in cows with low production. Very long fore udders usually produce more milk, what leads to a higher lifetime production.

Section 5. Appendix 5. Figure 22: Fore udder length
